D9.1. Within a certain region, € = 10-11 F/m and µ = 10-5 H/m. If Bx = JE 2× 10-4 cos 10³t sin 10-3y T: (a) use V x H = € to find E; (b) find the total at magnetic flux passing through the surface x = 0, 0 < y < 40 m, 0 < z < 2 m, at t = 1 μs; (c) find the value of the closed line integral of E around the peri- meter of the given surface. Ans. -20000 sin 105t cos 10-3 yaz V/m; 0.318 mWb; -3.19 V
